Personally this is not my experience. Plenty of seniors spitballing not useful solutions, premature optimization of sort etc...

The mid-career is perfectly fine, give you are also good at refactoring if needed.

Also, another thing that I'm not seeing stressed enough on this topic is: measure.

One thing I've found throughout my career is having Senior in your title is sometimes totally unrelated to your ability to write code or design solutions.
